MODE OF MAKING INLAID JEWELRY, 80C.

SPECIFICATION forming part of Letters Patent No. 254,945, dated March 14, 1882,

- Application filed January 3, 1882. (Nomodcl;

To all whom tt may concern I Be it known.that I, UHARLEs P. Fns'r, a cilizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Making Inlaid Jewelry, 8:0, of which the following is a. specification.

My invention relates to improvements in the method of makingjewelry, fancy buttons, and similar articles of mother-of pearl, ivory, boue,shell,preciousstones,orothersubstances, my invention having more particular reference to that class ofjewelry, buttons, 850., in which a substance of one shade or coloris inlaid into a substance of another shade or color, as more fully described hereinafter.

Inthe accompanying drawings, Figure 1 is a perspective view, and Figs. 2, 3, 4, and 5 sectional views, illustrating the steps of my improved process of inlaying; and Fig. 6, a. view of a finished article.

The drawings illustrate the method of male ing a mother-of-pearl button-for instance, by inlaying acentral ornamental piece of dark mother-of-pearl in a body ofligh t-colored pearl. I first lay on the body A a piece, B, of mother- 'ofpearl of the desired shade and ofa size sufficient for the inlay, and I preferably secure the piece 13 t0 the face of the piece A by cement. Then by means of a fine saw or other cuttingtool I cut outthrough the two pieces of pearl a piece, I) b, of the desired outline of the piece to be inlaid, the tool beingso held as to give an inclined cut and impart to the piece out out; a wedge shape, and the openingcut in the body A tapering from front to back. The outer portion of the piece B being now removed from the body A, the piece consisting of the front b,cut from the pieceB, and a back, I), cut from the body A, is reinserted into the opening formed in the body A. As the cutting out of this piece makes it smaller than the tapering opening to the extent of the thickness of the saw-blade, the front piece, I), as well as the back b, will fit into the body A, as shown in Fig. 3, being preferably secured by cement: The projecting portion of the piece b is Tlir'u ground or polished off flush with the body A, as shown in Fig. 4, and the projecting portion of the piece b, at the back, is also preferably polished off, as shown in Fig. 5; or it may be left in the condition shown in Fig. 4. If preferred, the two pieces I) b, after being cutout, may be separated, the piece b thrown away, and the piece I) inserted into the tapering opening in the body A alone, the recess left at the back being filled up by cement. The face of the button or piece ofjewelry may then be cut, engraved, or ornamented in any desirablemannor to finish the design, as indicated in Fig. 6.

In a former patent granted to me December 10,18I9,No.222,580, I described a method of making reliefjewelry by cutting out a piece of material on a bevel orin a conical form, and then projecting this-or a separately-cut; wedgepiece into the body thus cut out. In my pres ent invention I cut out the body-piece and the inlaid piece of different material at one operation, and insert the inlay into the body, and grind or otherwise make the surfaces of the two flush.

The advantage of cutting out both the parts, AandB, at one operation is that by that means an accurate fitting of the inlaidpiece with the body is obtained.

I claim as my invention- The. mode herein described of inlayiug pearl, ivory, shell, and similar substances with substances of another shade or color,.by first cutting out the two pieces in the desired outline at one and the same operation, leaving a tapering opening in the piece to form the body, and inserting the cut-out portion of the other piece into this opening, and finally making the surfaces of the two substances flush by grimling or otherwise, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
